Abstract:
Methods and circuits for storing column redundancy data are provided herein. A circuit may comprise a column redundancy data array, which may store an address and a plurality of match bits. A first portion of bits of the address may reference a range of columns of a memory array and a second portion of bits of the address may reference a division of the memory array in which a column of the range of columns is located. Each of the match bits may indicate whether one of the columns of the range of columns is defective.
